Hello,
Could you provide us more details on what happen when you try to launch Capella?

Hello,
I used Capella For 1 year now and since 3 days I Can’t open the executable. Nothing happensa that is the problem. I does not open the small block violet saying Capella in big letters.
My Capella aversion is 1.1.3. I have Windows 7 32 bits.
How can I re download Capella? I don’t understand what could happened.
Thank you

Hum it’s quite strange that it does not launch anymore if you didn’t change anything…
